All I know is that from a shell I can do:

	echo "You lost money" | mail -s "Lost money" fred

pretty easily.  Hard to make anything simpler that that, and I can't
imagine the other  languages are any faster or simpler.

I think sending email is an archetypal stored procedure action.  I
realize it isn't great, but it meets people's needs who have to do it.

You can argue that people shouldn't want to do such things, but they
obviously want to do them, so why not give them a way, and warn them at
the same time.
